To all whom z'zf may concern: y

Be it known that I, Jiissn BnMis, a citizen of the United States, residing at Belton, in the county of F latheadand State 'of Montana, have invented new and useful Improvements in Saw-Sets, of which the following is a speciiication. Y

his invention comprehends theprovision Y of a saw set which can be quickly and conveniently manipulated for the purpose in-A tended, and embodies among other features a trip hammer with means for holding the latter in predetermine. positions. to regulate the drop thereof consistent with the force required undeicertain conditions.

Another object of the invention resides in the provision of a manually controlled lever operable in-one direction to elevate the hammer, and adapted to be lowered against theV sa-w in its active position,.meansbeing employed for automatically holding the handle in any degree of elevation VVindependently of the hammer to permit the saw to be properly positioned therebeneath as the occasion may require. y

' The invention further contemplates the provision of a device of the above mentioned character wherein the lever is provided with one or more openings for the. reception of swaging elements of different characters for V use in connection with different type saws,

and wherein theswaging elements `are disposed in the path of mfovementofthe advantages of the inwenunderstood from the folwhen read in connection The nature. and

Fig. 9 shows several forms of swagin'g ele- 4Fig. 10 is av plan view of the anvil showing indicating marks thereon. efore entering into a detail description of what is herein shown and described I desire to have it understood that the same is merely illustrative of one embodiment of the invention .to w` lich I do not limit myself andt'hat such changes in the construction and arrangement of parts may be resorted to when desired as fall within the scope of what is claimed. It might further be started that the component parts 4of the invention may be constructed from any suitable material and design. Y As shown in this particular instance howeverthe device comprises a base 10 having suitable openings l1 adjacent the opposite ends thereoffoir the reception of suitable fastening elements for the purpose of securing the base to a suitable support. Rising from the base adjacent one end is a pair of spaced block-like members l2, and projecting forwardly from each block is abarlB disposed in spaced parallel relation to the base 10, and terminating an appreciable distance short of the forward end ofthe base. The space betweenthebaselO and the bars 13 is adapted to receive the body of the saw in a manner whereby the teeth can be singly disposed upon the anvil 14.- cairried by the base im- "mediately adjacent the forward end thereof in advance of the bars 13. The anvil may be provided with suitable indicating marks 14 thereon to act as guides for the teeth of the saw so as to secure an even setting for different saws, as shown in Fig. 10. T

Connecting the block-like members 12 is a bolt 15 constituting a pivot'for the, lever 16, the` purpose ofy which will be hereinafter more fully` described. The leveris bifurcated at the end which is pivotally associated with the bolt 15, and positioned between the separated portions 17 vdefined by the bifurcation is one end. of thetrip hammer, which is provided with a suitable opening 'for the reception of the bolt 15 upon which it is pivotally mounted independently of the lever 16. The hammer is disposed immediately above the lever 16 and as a unit is `approximately half the length of the latter, including a Cri ico

hammer is spring operated, a pair of fiat springs 19 being preferably employed, having their corresponding ends 20 secured to the upper surface of the block-like members 12, while the opposite extremities of the springs bear upon the cross pin 21 carried by the head 18 of the hammer, and are curved downwardly as at 22 to prevent separation of these pairts. The cross pin 21 is groove'd adjacent its opposite extremities, thereby defining shoulders 28 between which the free ends of the springs 19 are arranged and thus held against lateral movement as will be readily understood. The springs normally maintain the head 18 of the hammer in contacting engagement with the lever 16, which latter must be elevated to raise the hammer to its elevated 0r inactive position. Rising from the forward extremities of 20 the bars 18, and secured thereto in any suitable manner are spaced standards 24 between which both the lever 16 and trip hammer operates. The standards are provided with a longitudinal series of alined open- 25 ings for the reception of a pivot pin 25, and upon which is pivotally mounted a locking dog 26 for engagement with the head 18 of the hammer to hold the latter in elevated position. The pivot pin 25 may be secured between the standards in any suitable manner, and is preferably provided with a squared portion 27 which is received within the squared openings in one of the standards so as to prevent turning of the pivot, while the locking dog 26 has secured thereto a spring 28 having one of its ends passed through a slot 29 in the pivot pin 25, the spring operating to hold the locking dog in proper position so that its lowermost end will b e disposed in the path of movement ofthe head 18 of the trip hammer. The lower end of the locking dog is provided with a lip 80 adapted to engage within a groove 81 formed in the head 18 of the trip hammerto hold the latter in elevated position. The adjacent edge of the head 18 of the'` trip hammer is curved as at 82 to cooperate with the beveled portion 88 of the locking dog to prevent binding between these parts, thereby permitting the head 18 of the hammer to rock the lockingdog 26 upon its pivot asthe hammeris elevated, which places thespring28 under tension, so that thev spring functionates at the proper time to reverse the rocking. movement of the locking dogto bring the lip 80 into `effective enagement with the groove 81 and thereby hold the hammer in its elevated or inactive position.` As hereinabove stated the'lever 16 is pivotally mounted upon-the bolt 15 for movement independently of the trip hammer, and that subsequent` to elevating the lever for the purpose of moving the trip hammer to its inactive or elevated position,

the lever is then lowered into engagement be stated that the lever with the saw, which latter is positioned upon the base to be dressed. lt might here 16 at a point in its length carries Vva set screw 84 which can be properly adjusted to engage the body of the saw when the lever is lowered, to hold the saw immovably positioned upon the base. The lever is further provided with transverse openings 85 and 86 respectively to interchangeably receive any one of the swaging elements A disclosed in Fig. 9, whose uses are desired in connection with different type saws. These elements are interchangeably received by the opening 85, while the opening 86 is adapted to receive a relatively 80 broad swaging element A which is used only when it is desired to take the set out of the saw teeth for the purpose of sharpening the same. However when thev swaging elements are associated with the lever 16, and the latter lowered upon the saw, the swaging element engages the tooth of the saw immediately above the anvilrld, and is disposed in the path of movement of the head 18 of the hammer, so that when the 90 latter is tripped it isV effectively brought into engagement with the adjacent end of the swaging element, under the influence of the springs 19, thereby driving the element in the direction of the anvil to set the particular tooth of the saw being worked upon. Any suitable means may be employed for tripping the hammer, orV in other words movingfthe locking dog 26 out of engagement wi'h he head 18 thereof, but l pref- 100 v erably employ a flexible element 87 having one end secured to the upperjend of the locking dog 26 and itsopposite end secured to a trigger 88 pivotally mounted within a slot 89 in the lever an appropriate distance 105 in advance of the trip hammer; Y The flexible element is passed through an opening in the head 18 of the hammer, and also trained through a suitable guide 10 rising from said head. It is of course tobe understood' that when the lever 16 is raised to elevate'the hammer, the flexible element is slackened to permit the locking dog to be rocked upon its pivot in themanner hereinabove described during its association 115 with the head of the hammer, but when the lever is subsequently lowered to vits active position vagainst the saw, the flexible element is drawn taut, so that upon movement of the trigger in a downward direction, the locking dogv 26 is moved outof engagement with the head 18 vof the hammer through the instrumentality of the flexible element 87, thereby permitting the hammer to be forcibly actuated under tensionof the springs 19. Under certain eonditionsit is necessary to vary the force with which the hammer is lowered, and to provide for this, it is only necessary to position the pivotl pin 25 in any of the alined openings in the 13e a spring pressed lng `The standards are pref that the lockdog can be adjusted toward or away from the base 10 to hold the hammer in any degree of elevation, consistent with the force of the drop required under the circumstances. Manifestly with the adjustment of the locking dog 26 means must be rovided to regulate the length of the flexile element 3 and in this instance I preferably-secure the upper end of said element t0 a pin 4lV journaled between spaced apertured lugs rising from the upper end of the locking dog 26, so'that upon rotation of the pin in either one or the other direction, the flexible element is wound upon or unwound therefrom, thereby regulating the length .of the element so that the hammer can be easily and quickly tripped from any of its elevated positions. The pin is provided with a ratchet wheel 42 with which pawl 43 coperates to prevent retrograde movementof the pin. Subsequent to the locking of the hammer in elevated position, itis necessary to elevate the lever 16 to properly arrange or position the saw upon the base for the next operation ofthe hammer,-and,with a view of automatically holding the lever in elevated position, I preferably provide :the forward edge of one of the standards 24 with spaced grooves 44 to receive a spring operated roller 45 associated with the lever and effectively heldin engagement with the forward edge of said standards under the iniluence of the spring 46. The roller is jourstandards V24, that is to say naled in a frame 47 that is slidably mounted Within a longitudinally disposed groove 48 at one side of the lever and held in position therein by means of a guide 49 and the adjacent standard 24. The spring 46 as one end connected with the lever and its opposite end connected with the frame 47 and holds the roller in engagement with the forward edge ofthe said standard 24. erably curved as shown, and in addition to the roller holding the lever in elevated position, independently of the hammer, by'being positioned within one of the grooves 44, the roller allows the combined weights of the lever 16 and trip hammer to be easily and quickly elevated. Theframe 47 is provided with a finger engaging portion 50 which projects eyond one side of the lever, to permit the frame and' roller to be retracted to a position to clear the forward ends of the bar 13, while the lever is being singly lowered l to active position upon the base l0. In this position of parts the roller 45 under the influence of the spring 46\ is held in effective engagement with the forward end ofthe adjacent bar 13,.thereby assisting the set screw 34m holding the saw immovably positioned upon the base 10. The device is not only easy to manipulate, but the component parts `arecompactly arranged to produce both a simple and effective machine for the purpose intended.
